Job Details
Who is Sonar?
Sonar helps prevent code quality and code security issues from reaching production, amplifies developers' productivity in concert with AI assistants, and improves the developer experience with streamlined workflows. Sonar analyzes all code, regardless of who writes it — your internal team, genAI, or third parties — resulting in more secure, reliable, and maintainable applications. Rooted in the open source community, Sonar’s solutions support over 30 programming languages, frameworks, and infrastructure technologies. Today, Sonar is used by +7M developers and 400K organizations worldwide, including the DoD, Microsoft, NASA, MasterCard, Siemens, and T-Mobile.
We believe in developing great products that are supported by great internal teams and a strong culture. We are highly committed to and obsessed with the company, users, each other, and our open source community. We have high standards and hold each other accountable for acting with positivity, dedication, thoughtfulness, empathy, and passion daily.
We are deliberate with our decisions with high clarity of intention. At the same time, we feel extreme urgency and move forward quickly.
And lastly, we are highly effective and operationally efficient. We operate collectively as One Team to accomplish our goals.
At Sonar, CODE is more than just an acronym – it's a mindset that defines daily operations.
Why You Should Apply:
At Sonar, we’re a group of brilliant, motivated, and driven professionals working hard to help supercharge developers to build better, faster. Sonar helps to continuously improve code quality and code security while reducing developer toil. This means that developers can focus on doing more of what they love and less of what they don’t. Our solutions don’t just solve symptoms of problems – we help fix issues at the source – for all code, whether it's developer-written, AI-generated, or from third parties.
We have a dynamic culture with employees worldwide and hub offices in the USA, Switzerland, the UK, Singapore, and Germany. Team members should be able to come to work every day, work on a product they are proud of, love what they do, and feel energized by their peers. With our roots deep in the open source community, we’re all about the mission: supercharge developers to build better, faster.
The Impact You Will Have:
Join us in shaping the future of SonarQube and empower over 10 million developers worldwide to write cleaner, more secure code.

- Commitment to code quality, with hands-on experience in automated testing and CI/CD practices.
- Growth mindset and experience in mentoring, coaching, and elevating your teammates.
- Proactive problem-solving attitude, taking ownership of initiatives and driving them to completion.

- You validate assumptions, establish facts to guide better decisions, and proactively seek and provide feedback for growth.
- You tailor your message to your audience, inspire commitment, prioritize impact, and drive efficiency in collaboration.
Why You Will Love It Here:
- Our culture and mission set us apart. We have a dynamic work culture that values respect and kindness and embraces the right to fail (and get right back up again!).
- Great people make a great company. We value people skills as much as technical skills and strive to keep things friendly while still being passionate leaders in our domains.
